Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Cross-Site Request Forgery (CSRF) vulnerability in Anps Constructo constructo allows Object Injection.This issue affects Constructo: from n/a through <= 4.3.9.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A Cross-Site Request Forgery (CSRF) vulnerability in Anps Constructo CMS (versions up to 4.3.9) allows attackers to trick authenticated users into performing unintended actions that trigger PHP Object Injection. This occurs because the application lacks proper anti-CSRF tokens on state-changing operations, combined with unsafe deserialization of user-controlled input, potentially enabling remote code execution or data manipulation.

MitigationImplement anti-CSRF tokens on all state-changing operations and validate/sanitize all user inputs to prevent unsafe object injection. Review and restrict deserialization to whitelisted classes only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Determine installed Anps Constructo CMS version
    Locate the version identifier in the CMS installation, typically found in the admin dashboard under 'About' or 'System Info', or check version.php/version.txt in the web root directory
    Affected if The installed version is 4.3.9 or any earlier version (versions up to 4.3.9 are affected)
  2. Identify state-changing operations
    Review application forms and AJAX endpoints that perform database writes, user management, content updates, or configuration changes
    Affected if The application lacks anti-CSRF tokens (such as hidden form fields or request headers) on these state-changing operations
  3. Inspect deserialization implementation
    Search the application source code for usage of PHP deserialization functions (unserialize) that process user-controlled input from request parameters, cookies, or stored data
    Affected if The application uses unserialize() on data that can be influenced by users without class whitelist restrictions
  4. Verify user input reaches deserialization
    Trace the data flow from user inputs (POST/GET parameters, cookies) to deserialization functions to confirm attacker-controlled data can reach unsafe unserialize() calls
    Affected if User-supplied input is passed directly to unserialize() without validation or restriction to safe classes

A user is affected if running Anps Constructo CMS version 4.3.9 or lower AND the application performs unsafe deserialization of user input on state-changing operations that lack CSRF protection.
